Elizabeth Percy, Duchess of Northumberland (1716–1776)

Elizabeth Percy, Duchess of Northumberland (née Seymour; 26 November 1716 – 5 December 1776) was a British peeress. She was the wife of Hugh Percy, 1st Duke of Northumberland, and a major figure in 18th-century British high society.

Born Elizabeth Seymour, she was the daughter and sole heir of Algernon Seymour, 7th Duke of Somerset. Through her father, she inherited vast estates and considerable wealth, which significantly enhanced the Northumberland family's standing.

In 1740, she married Sir Hugh Smithson, 4th Baronet, who, upon inheriting the Earldom of Northumberland in 1750, took the surname Percy in accordance with the will of his father-in-law. This revitalized the ancient Percy lineage, which had been in abeyance. He was later created Duke of Northumberland in 1766, making Elizabeth the Duchess.

As Duchess of Northumberland, Elizabeth was a prominent hostess and patron of the arts. She was known for her lavish entertainments at Syon House and Northumberland House. Her circle included artists, writers, and prominent political figures. She also oversaw significant improvements to the family's estates, including gardens and architecture.

Elizabeth Percy was a Lady of the Bedchamber to Queen Charlotte. She was also renowned for her correspondence and diaries, which provide valuable insights into the social and political life of the Georgian era. Her legacy includes the revitalization of the Percy name and the creation of a significant cultural and social hub around the Northumberland family. She and the Duke had several children, including Hugh Percy, 2nd Duke of Northumberland.
